Be it known that I, JAMEs M. EVANS, a citizen of the United states, and resident of Westport, in the county of Fairfielch State of Connecticut, have invented certain new and useful Improvements in Garbureters, of

gines, apparatus or OOIltIiYELIlCQS for generating power, or for enriching. gases for illuminatlng, heating or other purposes, or for obtalning a mixture of any liquid, finely separated or] vaporizecL-with any gas; for

any purpose for which such an admixture of liquid and gas maybe desired,

. I accomplish these objectsjby a noveldevice or arrangement, comprising a reservoir for fuel, a mixing chamber in which the liquid is delivered in measuredcharges and mixed with the air or gas and a rotary conveyer preferably in the form ofarotary disk, having. recesses formed in its periphery adapted to ibeopened inthereseryoir and to receiye the charges sand to be. closed in the mixing chamber, thereby forcibly ejecting and delivering the chargesto said cham- 706i" p .1. Among the many purposesfor which this a device is adapted for use is the productionof an; explosive gas for the operation of inter- -1'1al combustion engines through the mixing of a liquid fuel; such as gasolene, kerosene, alcohol or any other volatilefluid hydrocarbon with atmospheric air in the proper portionsfor explosion insueh engine g and I shall describe the operation of my device with such an engine, butitsuse isby no means limited to such engines, although the ing. the recesses at the periphery of the disk.

general method ofoperation with respect to other uses is similar to that about to be described. I A

v the drawing accompanying and forming part of this specification I have illus trated the preferred embodiment of my invention, and the construction, operation and advantages of .my improved device will readily be understood from an explanation of these drawings. I U

Referr ng to the drawings: V I Figure 1 1s a sectional .viewof my im- .proved device shown attached to the intake pipe or manifold of a gas engine, which intake pipe oi'manifold constitutes the mixing orcarbureting chamber of the device. H 2 and 8 are sectional views of the im proved devise, showing the rotary disk employed to convey the liquid from the reservoirtothe mixing chamber, in two operative positoins. v k

Figs l and 5 are detail views showing the mechanism employed for openingand clos- Referring. now in detail to. these drawings, the numeral 1 designates the liquid reseryoir to which liquid is supplied through the pipe 2 and maintained preferably under slight head or pressure, The numeral 3 designates the mixing or carbureting chamber. The carrier of liquid from the reseryoir to the chamber 3 comprises two plates el and 5 mounted; on the shaft 6 and adapted to .rotate bletween the fixed plates 7 and 8. The platel is provided with a flange 9 located on the face of the plate and extending slightly less than half around the plate. The plate 5 isalso provided with a flange 10 and this flange is also located on the face of the plate and extends slightly less than half around the same. ,When assembled, the flanges 9 and 10 each oyerhang the'outer edge of the oppositely disposed plate and the two plates form a smooth disk, except for the recesses at the ends of thefianges. Means are provided to move the two lates with respect to each o ther they rotate onthe shaft 6, in order that the adjacent ends of the flanges 9 and 10 may be made to move away from or is. forced, and then to hold this relative position until the charge has been brought into the mixing or carbureting chamber where the ends of the flanges approach each other and forcibly eject the charge. To this end a bell-crank 11 is provided and disposed in a recess 12 in the plate 5. This bell-crank is provided with three arms. One of these, 13, is pivotally secured to the disk 4, and another, 14, is pivotally secured to the disk 5, while the remaining arm 15 is pro vided with a projection 16, adapted to move in the cam groove 17, formed in the fixed plate 8, as the bell crank as a whole rotates with the disk. The cam groove 17 is so shaped that as theshaft 6 rotates and the adjacent ends 18 and 19 of the flanges 9 and 10 approach and enter the liquid reservoir, the plate 5 will move ahead of the plate'i which is keyed on the shaft 6, and the ends 18 and 19 of the flanges will separate and form a recess as shown at 20 in Fig. 3. The liquid will be drawn or forced into the recess and will be carried around in the same until the liquid is in the mixing or carbureting chamber 3. The cam groove will then actthrough the bell crank and bring the ends together, thereby forcibly ejecting and spraying the liquid. In the continued rotation of the shaft 6, the recess is again opened in the reservoir, and the above cycle of operation is repeated. In the particular arrangement described. there are two sets of flange ends on each disk and the arrangement is such that when one set of ends approaches in the mixing or carbureting chamber and closes the recess so as to eject and spray the liquid, the oppositely-disposed ends of the flanges separate and form a recess in the liquid reservoir which is filled with a charge of fuel.

It will be observed that in the operation of the device, the component parts of the disk, which cooperate to form the recess, are submerged in the liquid in closed relation. They then open, forming a recess of definite sizeinto which a uniform and definite quantity of liquid is received. The component parts in which the recess is formed then pass bodily through a passage and carry and deliver this measured chargedirectly into the mixing or carbureting chamber throu h i which, in the example chosen for illustration, a current of air is passing on its way to the engine. They then close and forcibly eject the liquid. The device therefore operates to deliver uniform and charges of liquid directly into the air in the mixing or carbureting chamber. This method of operation renders my device free from any irregular action incident to the use of pumps with valves and to jet carbureters which depend upon suction or upon partial vacuum for operation. 'It is also independmeasured ent of atmospheric pressure and does not require regulation, because of changes of atmospheric pressure.

This application is a division of an application heretofore filed by me, Serial No. 866,276, filed October 12, 1914, and is filed in order that I may make claims relating specifically to the mechanism operating on the rotary principle, described above.

WVhile I describe in this application only the preferred embodiment of my invention, I am aware that many modifications may be made by those skilled in the art, without departing from the-scope of my invention.

What I claim is:

1. In combination in a device of the kind described, a reservoir chamber for liquid, a mixing chamber, for the passage of air or other gas, a passage connecting the two chambers, a' disk mounted in said passage and having a recess formed in its body, means forrotating said disk whereby the recess is made to move from one chamber to the other, and means for opening the recess in the reservoir chamber to receive a charge of liquid therefrom, and for rapidly closing said recess in the mixing chamber, to forcibly spray the charge thereinto.

' 2. In combination in a device of the kind described, a reservoir chamber for liquid; a mixing chamber, a carrier of measured charges of liquid from one chamber to the other; comprising a rotatable disk formed of two plates, having recesses at its outer edge and means for moving the plates with respect to each other, whereby the recesses are opened and closed, for the purposes described.

3. In combination in a device of the land described, a reservoir chamber for liquid, a mixing chamber, a carrier of measured charges of liquid from one chamber to the other, comprising a rotatable disk having a plurality of recesses disposed about its periphery, and means for opening the recesses in the reservoir chamber, to receive charges of liquid therefrom, and for rapidly closing the recesses in the mixing chamber to forcibly spray the charges thereinto.

4. In combination in a device of the kind described, a reservoir chamber for liquid, a mixing chamber, a rotatable disk so disposed that its periphery moves through both chambers, means for rotating said disk, means for opening a recess at the periphery of said disk, in the reservoir chamber, to receive' a charge of liquid therefrom and for rapidly closing said recess in the mixing chamber to forcibly spray the charge thereinto.

5. In combination in a device of the kind described, a reservoir chamber for liquid, a

mixing chamber for the passage of air or other gas, a carrier of measured charges of liquid from one chamber to the other, comprising a rotatable member having a recess therein, means for opening the recess in the reservoir chamber to receive a charge of liquid therefrom, and for rapidly closing the recess in the mixing chamber to forcibly spray the charge thereinto.

In testimony whereof I have signed this specification 1n the presence of two subscr1bing Witnesses.
